Shortly after the original divorce filing, Silva claimed that he had every right to keep the guitar because Frances Bean had given it to him as a wedding present. She claims she did no such thing. Originally given to her for safekeeping, the guitar is thought to be worth millions of dollars.

The guitar is one of about 300 made by the company before the model was discontinued. It’s even more unique because it has a replaced bridge and nut that allowed for the left-handed Cobain to play it. According to Cobain’s ex, Courtney Love, it’s also the last guitar he played months before dying by suicide in 1994.
